NAME
gpsinterface - Generic PostScript model for System V spooling.
DESCRIPTION
gpsinterface is a model file based on Sys V spooling for Serial
PostScript printers. gpsinterface provides a mechanism for printing
normal ASCII text, PostScript, and RGB image data to a PostScript
printer.
While adding a new printer using System Manager Tool , choose Generic
PostScript Type for selecting gpsinterface. The gpsinterface processes
the input data and invokes the appropriate filters to convert the input
data into printer language PostScript.
The gpsinterface invokes lptops filter to convert normal ASCII text to
PostScript. The lptops filter supports selection of a variety of fonts
at arbitrary point sizes, margin specification, portrait and landscape
page orientation, automatic page numbering, page outlining, and multi-
column printing. It can also handle overstruck text used by many
document formatters for underlining. The user can select the different
options through -o option of System V lp command.
In the option descriptions below, physical dimensions described as # may
be specified as a single number with an optional fractional part, and a
required two-letter unit designator. Letter case is ignored. Possible
forms are:
#.##bp big point (1in = 72bp) [Courier: 120.000/Pbp cpi]
#.##cc cicero (1cc = 12dd) [Courier: 9.381/Pcc cpi]
#.##cm centimeter [Courier: 4.233/Pcm cpi]
#.##dd didot point (1157dd = 1238pt) [Courier: 112.569/Pdd cpi]
#.##in inch [Courier: 1.667/Pin cpi]
#.##mm millimeter (10mm = 1cm) [Courier: 42.333/Pmm cpi]
#.##pc pica (1pc = 12pt) [Courier: 10.038/Ppc cpi]
#.##pt point (72.27pt = 1in) [Courier: 120.450/Ppt cpi]
#.##sp scaled point (65536sp = 1pt) [Courier: 7.893/(Psp/1000000) cpi]
The bracketed values give the number of characters per inch (cpi) for a
point size of P units with the fixed-width Courier font. For example,
with point size 8bp, there are 120/8 = 15 characters per inch. With
point size 1000000sp, there are 7.893 characters/inch.
The letter case is ignored in the options, and the following options may
appear in any order.
-a Turn Scribe-like bold and italic requests (@b[...] and @i[...]) into
bold or italic text.
-b# Bottom margin of #.

-cn Print n copies of each page.
-ffontname
PostScript fontname. Possible values with acceptable short
abbreviations (formed from the upper-case letters in the font
names) are as follows. The first 13 are available on all
PostScript printers; the remainder are available only on enhanced
printers, such as the Apple LaserWriter Plus.

Only the Courier fonts are fixed-width like typewriter and line
printer fonts are. The others are proportional spaced for
improved readability, and consequently, tabular material will

not line up properly with them. The Courier fonts have a width
equal to 0.6 of their point size, so to fill a line W inches wide
with up to N characters, one must have point size <= (W/(0.6 * N
* 72)) = (W*120)/N pt. Equivalently, with a point size P pt, the
output spacing is 120/P char/inch.
-h Horizontal page orientation (landscape mode) instead of vertical
page (portrait mode).
-i# Top margin of # for initial page (for letterheads); if not
specified, it will default to the value given for the top margin
by default or by the -T# command.
-l# Left margin of #.
-mn Multiple column output (n columns). In multiple column mode,
formfeeds cause column breaks instead of page breaks.
-n[tb][lcr]n
Number output pages. The number is placed by default in the center
of the top margin, but the margin can be selected explicitly by
t (top) or b (bottom), and the position of the page number can be
further specified by l (left), c (center), or r (right). If n
is given, start numbering with that value, and otherwise with 1.
If an initial top margin value is given with the -I# option,
numbering will be omitted on the first page if it is at the top.
Pages are unnumbered if this option is not specified.
-o[#]
Outline pages (and columns) with a # units wide. A narrow line
of 0.4pt width is assumed if # is omitted; this particular width
is what TeX uses in typesetting.
-p# Font point size (default 10bp). The baseline skip (spacing
between successive character baselines) is conventionally chosen
to be 6/5 of this value, so that with 10bp type, we have 12bp
between lines, or 6 lines/inch, the same as standard printer
output.
-r# Right margin of #.
-t# Top margin of #.
-u Output pages in unsorted (first to last) order instead of in
sorted (page reversed) order; some PostScript printers have page
handlers that stack the paper in this order. The default is
sorted because this is appropriate for the most common
PostScript printer, the Apple LaserWriter.
-v Vertical page orientation (portrait mode) instead of Horizontal
page orientation (landscape mode).
